195 single axle trailer bearings

[avlryan]

I picked up a Scarb 2019 195 Wake Edition last year. I was prepping the trailer for a long trip and discovered that one of the outer bearings was destroyed. The trailer is the black Scarab single axel version. Does anyone know what parts I need to replace them? It would be great to get a kit with everything.

Thanks!

A lot of manufacturer of trailers use universal hubs and bearings. Look at the axle on the trailer. There should be a sticker that has the load rating of the axle. The hub assemblies will match this rating. These can be found at a place such as Northern Tool. The entire hub assembly is not expensive and comes comes pre-greased. The entire replacement job takes less than an hour. Just remember, there is a retaining washer behind the axle nut you'll need to reuse (it also aids in seating the bearings of the hub assembly on the axle.

Thanks for the info. I think I found that it uses 25580 for the inner and 15123 for the outer. I'll check out the hub assemblies as well. That sounds easy enough.

I'd be interested in where you get the bearings, specific part numbers, and as detailed a description as you are willing to provide for replacing the bearings (including pictures). One of my bearings seems to be running hot, and I've contemplated replacing it.

I also found this information that came with my single axle, gatorhyde coated, Scarab 195G trailer, in case it's of any value.

I ended up ordering this kit from Amazon, which has 25580 for the inner and 15123 for the outer. The bearings fit fine, but the dust cover is too big, so I had to use the old one. I damaged the original plastic inner grease seal trying to remove it and used the metal one from the kit. I'm not sure if the seal is shallower, or if it's just not supposed to be pressed in all the way, but it went in farther than the edge of hub.

I only replaced the side that was destroyed. At some I'll replace the other side and pay better attention to how it is setup. For example, I'm wondering if it had a metal grease seal, like the one in the kit in addition to the plastic piece. I don't remember seeing anything like that, but I could be wrong.

So is the correct process?

1. Remove lug nuts.
2. Remove wheel.
3. Move brake caliper off of brake disk.
4. Remove castle nut.
5. Remove hub.

Additional questions:

How much effort is required to remove the hub?

Will I need to tap it a bit from behind to remove the hub?

Is the brake disk integral with the hub?

Thank you for any responses. I’m just trying to understand what I’m getting into, since I haven’t done this before.

I'm not the best person to give advice about this since it was my first time. I watched couple of videos about it like this one, but you will have the extra steps of dealing with caliper. I'll give my experience, but maybe someone that knows what they are doing will chime in.

Those steps sound right for the removal. There is also a pin that holds on the castle the nut. The brake rotor is integral with the hub. My trailer has metal brake lines, so I was careful not to move the caliper very far. I just supported it securely so it wouldn't fall and kink the line.

The hub came off easily for me, but I think that was because one of the bearings was in pieces. Nothing was hard, but the two things that took the most time were getting the dust seal off and getting the caliper back over the disc.

On the dust seal, I started with a screwdriver, but I think I ended up using a large socket on the inner bearing to push both the bearing and seal out.

To get the caliper back over the rotor, I removed the brake fluid cap and slowly compressed the piston a little with a clamp.

Were you able to find a kit made specifically for the hub? I was in a rush because of an upcoming trip so I ordered the amazon kit. I wish I could have found something made specifically for this hub.
